Auxiliary seat pad for an invalid

ABSTRACT

An auxiliary seat pad invented for an invalid to sit on a toilet, a stool and a chair, with which offers a higher seat position, safety, easy assembling, comfortable contact, and durability, comprises a rigid support plate, a stuffing body with the determined thickness deposited on said support plate, and a soft elastic enclosed body with a certain thickness to enclose said support plate and said enclosed body. With a set of adjustable clamping apparatus on the bottom side, secures said auxiliary seat pad on a toilet.

FIELD OF THE INVENTION

The present invention relates to a seat pad, and particularly to anauxiliary seat pad on a toilet, a stool and a chair to assist seatingfor an invalid with less strength, safety and comfort.

DISCUSSION OF THE BACKGROUND ART

Conventional raised toilet seat have been invented as an auxiliary foran invalid whom is difficult to use an ordinary toilet, with which aninvalid can get up and sit down with less strength. For examples of someof such prior invention are shown in patents to Locarno, U.S. Pat. No.5,027,445; Locarno, U.S. Pat. No. 5,199,112; Hunt, U.S. Pat. No.D489,438. However, they were made in a rigid material, which wereuncomfortable and dangerous for an invalid to use in a slipperybathroom.

There were also some prior arts of the cushioned seat invented for asoft and comfortable toilet seat as shown in patents to Ginsburg, U.S.Pat. No. 3,949,432; Ginsburg, U.S. Pat. No. 4,248,646; Hicks, U.S. Pat.No. D390,644; Wang, U.S. Pat. No. 5,991,935; Orgias, U.S. Pat. No.6,330,723; White, U.S. Pat. No. 6,370,704. The conventional cushionedtoilet seats are formed of three layers: a base; an insert disposed onthe top surface of the base; and an outer cover layer affixed to thebase. Basically they are invented for a normal user. Therefore, they areemphasized on the softness and comfort, for which doesn't suit for aninvalid whom asks for a safe and strength less seat.

Considering the above arts, the present invention of an auxiliary seatpad can benefit for an invalid to sit with less strength, safety andcomfort. The purposes of the present invention are shown as following;first, offering a soft touching raised pad with certain elasticity andplasticity for assisting an invalid comfortably, safely and with lessstrength to sit on a toilet, a stool and a chair; second, a waterproofventilated texture surface which is easy maintaining, washing andpreventing the user's skin to sweat and skid; third, at least a set ofthe clamping apparatus set on the bottom of the auxiliary seat pad,which is convenient to operate and affix on a toilet bowl.

SUMMARY OF THE INVENTION

Briefly described according to the first preferred embodiment of thepresent invention, an auxiliary seat pad comprises a support plate, astuffing body, an enclosed body, and a set of the clamping apparatus.The detail description of each part of said auxiliary seat pad is asfollowing:

A support plate is a rigid annular plate as a base to stand the weightof an invalid, and join with a set of the clamping apparatus.

A stuffing body is modeled a thick light stuff and deposed on saidsupport plate, with which form offers to raise up the surface of sittingpart for an invalid to sit and bend his /her knee with less strength.

An enclosed body is a foamed elastic stuff to enclose said support plateand said stuffing body with a ventilated texture on the surface, withwhich the gooseflesh-like texture offers a dry and skid proof contactsfor an invalid, and prefers a waterproof material which is convenientfor washing and cleaning. An inner peripheral flange of said enclosedbody inserts to said toilet bowl.

The density of a stuffing body is relatively opposite to an enclosedbody, for example, a lower dense stuffing body enclosed by a higherdense enclosed body, and a higher dense stuffing body enclosed by alower dense enclosed body. Therefore, the auxiliary seat pad offerscertain softness and maintains a form for an invalid to sit on it.

A set of the clamping apparatus set on the bottom of said auxiliary seatpad, for which clamps on the outside edge of said toilet, and a blockerset on the front bottom side of said auxiliary seat pad, cooperate tosecure said auxiliary seat pad on the top of said toilet.

The second preferred embodiment of the present invention, an auxiliaryseat pad modeled to a round shape without a center hole for depositingon a stool or a chair comprises three layers which are correspondent tosaid first preferred embodiment with a rigid support plate, a stuffingbody and a enclosed body.

The third preferred embodiment of the present invention, an auxiliaryseat pad modeled to an annual shape as same as the preferred embodimentfor depositing on a toilet without a set of the clamping apparatus.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

As shown in FIGS. 1 to 5, the first preferred embodiment of the presentinvention for a toilet, an auxiliary seat pad 100 comprises a supportplate 10, a stuffing body 20, an enclosed body 30, and a set of theclamping apparatus 40. The detail description of each part of saidauxiliary seat pad is as following:

As shown in FIG. 4 and 5, a support plate 10 is a rigid annular plate asa base to stand the weight of an invalid user, and sets a pair of screwhole 341 and limit hole 342 for joining with the guide bases 41.

As shown in FIG. 4, a stuffing body 20 is modeled in a annular layerwith the thick light material and deposed on a support plate 10, withwhich a determined thickness raises up the surface of sitting part foran invalid to sit and bend his/her knee with less strength.

As shown in FIGS. 1 to 5, an enclosed body 30 is a foamed elasticannular layer to enclose a support plate 10 and a stuffing body 20 witha ventilated texture 31 on the surface, with which the gooseflesh-liketexture offers the dry and skid proof contact for an invalid, andprefers using a waterproof material which is convenient for washing andcleaning. With certain thickness the enclosed body 30 soften the contactand last the usability. On the bottom inner edge of the enclosed body 30is formed with a peripheral flange 32 for inserting to a toilet bowl.Therefore, the inner periphery 110 of the enclosed body 30 can connectwith the inner bowl of a toilet. The density of a stuffing body 20 isrelatively opposite to an enclosed body 30, for example, a lower densestuffing body 20 is enclosed by a higher dense enclosed body 30, and ahigher dense stuffing body 20 is enclose by a lower dense enclosed body30. Therefore, the auxiliary seat pad 100 can offer the softness andmaintain a form as an invalid to sit on it.

As shown in FIGS. 1 to 5, a pair of the clamping apparatus 40 set on thebottom of the auxiliary seat pad 100 cooperates with a blocker 33 set inthe front bottom side to clamp and fix on the outside periphery of atoilet bowl. A blocker 33 is an extension of the support plate 10 andenclosed by the enclosed body 30 to block on the front edge of thetoilet bowl. On the bottom of the enclosed body, there are twoindentations 34 with a screw hole 341 and a limit hole 342 on each,which are set into the support plate 10, for screwing and joining theclamping apparatus 40 on it. A clamping apparatus 40 comprises a guidebase 41 and an L-shape block 42 with a fasten screw 422.

As shown in FIGS. 5 and 6, a guide base 41 comprises a hole 412 forinserting a screw 43 through into a screw hole 341, a limit post 413 forinserting to a limit hole 342 on a indentations 34, and a guiding notch411 with a thread of the screw 414 for guiding one end 421 of theL-shape block 42 with a fasten screw 422 to screw into.

As shown in FIG. 6, a L-shape block 42 comprises one end 421 of theblock with a notch for which a fasten screw 422 inserts through, and theother end 423 of the block with an elastic pad 424 for which increasesthe attachment as a fasten screw screwing into a guide base 41 andforcing the L-shape block 42 to clamp a toilet bowl.

As shown in FIG. 7, an alternative embodiment of a pair of clampingapparatus 40 comprises a pair of L-shape block 42, a pair of fastenscrew 422, and a pair of guide base 41 which is modeled a part of thesupport plate 10.

As shown in FIG. 8, the second preferred embodiment of the presentinvention, an auxiliary seat pad modeled to a round shape without acenter hole for depositing on a stool or a chair comprises three layerswhich are correspondent to said first preferred embodiment with a rigidsupport plate, a stuffing body and a enclosed body.

As shown in FIG. 9, the third preferred embodiment of the presentinvention, an auxiliary seat pad modeled to an annual shape as same asthe preferred embodiment without a set of the clamping apparatus fordepositing on a toilet.
